T0 all whom t may concern.'

Beit known that we, BENJAMIN F. LAU' DENSCHLAGER and JOHN S. FREDERICK, both citizens of the United States, and both residing in Emaus, in the county of Lehigh and State -of Pennsylvania, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to window screens of the kind comprising a suitable frame' covered with wire gauze or other reticulated fabric serving to exclude dust, insects, etc., and also to protect the window from the entrance of small animals and unauthorized persons.

The object of the invention is to provide a screen of this class which may be easily placed in position or taken down and which is provided at the bottom with a movable portion which may be opened without moving the body of the screen to fasten and unfasten the shutter locking and operating devices and to also operate the slats of the shutters when such shutters are provided with slats.

Another object of our invention is to provide a screen which covers the entire win,

purposes and may be readily removed from the window when it is not needed.

Another general object of our invention is to so mount the screen in the window frame that it shall occupy as li"y ';le space as possible and yet `shall be suficiently heavy to be strong and durable.

Other features of our invention will be hereinafter described.

In the accompanying drawings, Figure 1 shows a vertical section of a window and screen embodying our improvements. Fig. 2 is a perspective view of a screen constructed in accordance with our invention adapted to be supported on hinges which permit the screen to swing open to expose the upper and lower sashes. Fig. 3 is a deta1l view in section on the line 3-3 of Fig. 1. Fig. 4 shows a section on the line @i-L of Fig. 1. Fig. 5 is a detail view show- 1ng partlcularly how the slats of the shutters are operated and how the lower portion of the screen is opened to permit access to the shutter operating andl fastening devices and the Slat-adjusting mechanism. Fig. 6 is a detail View of one of the shutters with the Slat-operating mechanism applied thereto. Fig. is a perspective view of a hinge whichmaybe employed. Fig. 8 is a perspective view of what is called a half-screen, that is, a screen which covers only the lower portion of the window frame. Fig. 9 is a perspective view of a modified construction. Fig. 10 shows how our improvements may be vapplied to a window frame having an arched top. Fig. 11 is a detail view in section showing more in detail certain features of construction of the lower hinged portion of the screen. Fig. 12 shows in vertical section how an awning may be mounted'on a screen which isv hinged to swing outward about a vertical axis with the awning and it .also shows how the awning may be operated without disturbing thescreen. Fig. 13 is a view partly in elevation and partly in section of the features shown in Fig. 12. Fig. 14 illustrates how an awning may be applied toa screen mounted in a window having an arched top.

The window frame may be of usual construction, the lower sash A andthe upper sash B being made to slide vertically in the usual way.

a indicates a handle for lifting and lowering the lower sash.

c indicates strips for guiding the sashes.

The shutters D are hung by hinges d as illustrated and the screeen E is located behind both the upper and lower sashes and inside the shutters D.

The screen shown in the first siX figures of the drawings comprises a frame having sides e, a top` cross-piece e', a bottom crosspiece e2 and a cross-piece e3 arranged midway between' the top and bottom of the screen. The wire cloth E covers the frame in the usual way. The top of the screen frame bears against the top of the 'window frame, but the bottom of the screen termiopening which provides access to the shutter operating and fastening devices and also to the slat-adjustino devices. rlhis opening 1s, however, closed a lid G shown as-consisting of a box closed at opposite ends and hinged at g to the lower cross-piece of the screen frame. rlhe box is preferably provided on its front side with a screen, g of wire cloth or the'like and it iarries knobs or handles g2 by means of which the lid may be opened and closed. 'llhe box may be constructed partially of wood and partially of metal. It extends from'one side of the'window to the other and the sides of the box are preferably closed by sheet metal plates g4, g5. rlhe plate g4 may, as shown in Fig. 4, be straight or at right angles to the front of the box, but the plate g5-is preferably set at an angle as shown in Fig. so that when the screen is opened or swung on its hinges as hereinafter described there will be a sufficient clearance for the screen to open easily.

The screen as a whole is hinged to the window frame as shown. Preferably` the stationary hinge members z, are attached to a strip H secured to the window frame and the hinges are. of such construction that the screen may be easily placed in position or taken down whenever desired. rl`he otherv members h ofthe hinge are attached to the screen frame in the manner indicated in Fig. 2 and these hinges are of such construction that while they permit the screen to be swung open or closed, they also permit the screen to be lifted off from the stationary hinge members 71, whenever desired. The particular construction of hinge Vand the vmanner in which it is mounted is claimed in our co-pending application for Patent No. 112,992, filed Aug. s, i916.

When the screen cis closed it is fastened by spring bolts I of wellknown construction. It will therefore be understood that the entire window opening is screened. The sashes may be raised and lowered without interference with the screen. enever it is desired to open and close the shutters, the lower sashl ma be raised and then the lid G may be lifte whichaa'ords easy access to the shutters from one end of theV window opening to the other. The opening is therefore largev enough to permit of the slats of the shutters being operated and of the shut-l ters being taken hold of close to the hinges, or otherwise should the shutter-operating devices fail tovoperate. When it is desired yto clean the window the screen-as a whole may be swung onits hinges after the shutters are opened, thus exposing the entire outside of the sashes for cleaning purposes.

When the box or lid G is opened, as indicated in Fig. 5, it may be held in its open position by means of a spring catch F, Fig. 5, which presses against one side of the lid Lacasse to the sill of the window and may be easily reached when the lid Gr is opened. As shown in the drawings the slats d are connected by rods d2. and to these rods are connected wires d3 which are guided by eyes dt and which have inwardly projecting handles d5.

lt will readily be seen that by lifting and lowering these handles the /slats may be opened and closed. The wires d3 are bent as shown and are so attached to the slats that when the slats are closed the rods df will be turned so as to occupy as little space as possible.

When the Slat-operating devicesare ernployed we form recesses el in the cross piece es as indicated particularly in Fig. 2. rlhis is also shown in Fig. l-where the rods d2 are shown as passing through said recesses. In this way space is economized.

`When recesses el are employed we strengthen or reinforcel the cross-piece e3 by a metal cross-piece e, shown most clearly in-Fig. 2. lnasmuch as the rods d2 extend below the bottom cross-piece e2 we also form recesses e12 in this bottom cross-piece as shown in Fig. 2. ln this way the presence of the slatoperating devices doesnot in any way cause additional space to be occupied.

When the window frame is of considerable width we preferably strengthen the box ico or lid G by a brace m, as indicated in Fig. l,

although this is not always required. Such brace is located in shown in Fig. 2.

The shutter-fastening and operating derear of the panelY vices are shown at J and these may be of usual construction. It will be observed that such shutter ,operating and fastening devices extend into the box or lid and that the box or lid is located in the vsame vertical plane ,as the upper sash, being mainly directly below the upper sash, itsfront portion being quite close to the lower sash.

Therefore this box or. lid/occupies no extra space.

W'hile we preferably provide the front of the box or lid with Wire gauze, asillustrated, this portion of the lid may be closed in the manner indicated in Fig. 9.

The frame of the screenjis sometimes apt to warp or buckle and dto press against .the sashes. ln order to prevent this we provide one or more stops K, see Fig. 3, which is attached to the window frame and has a portion 7c against which the front or inner side of the frame abuts. This will prevent the frame of the lscreen from coming into contact withthe sash frame.

Fig. 7 of the drawings showsthe form-of hinge which we preferably use for hanging the screen on the window frame; It will be observed that the hinge comprises a member 71. adapted to be attached to the window frame and a member la. adapted tobe attached to the screen and that the member h may be readily separated from the. member" 71.. As described in our application just referred to the hinge is of such construction that the joint or knuckles may be set in a recess in the frame so that space is economized. y .1

j Fig. 8 of the drawings shows a screen similar to that before described except that it is what is known as a half screen and it is adapted to cover only the lower portion of the window opening. As the parts are similar to corresponding parts before described they are similarly lettered.

Fig. 9 shows a construct-ion similar to that before described except that the front of the box or lid is not provided with wire gauze. v

Fig. 10 illustrates how our improvements may be applied to a window frame in which the top is curved or arched.

Figs. 12 to 14 show how an awning may 'be attached to the screen in -such manner that when the screen is opened the awning is swung out of the way with'the screen.-

The screen may be constructed in the manner before described, or it may be in the form shown in Fig. 12. As illustrated the screen M is mounted to swing on hinges m and is provided with a suitable fastening `device m. The awning N is attached at n tinuous. It is attached at 0 to the awning and it passes over pulleys p, p and through an opening o in the top piece of the screen f1 ame. The rope also is guided by a-pulley o2 on the bottom piece of the screen frame and passes through an opening o3 therein. The rope also passes through an opening 1' in a cross' piece ll" attached to the middle cross-piece 1'2 of the "screen, piece 7" lls the gap between the cross-piece r2 and the lower cross-piece of the upper sash and should a half screen only be used it prevents insects, &c., from finding their way over the top of the half screen and down under the upper sash.

Fig. 18 merely shows an elevation of what is shown in Fig. 12.

Fig.. 14 merely shows that our improvements may be applied to a window having an arched top.

It will be observed that care has been taken to economize space as much as possible and yet the sashes may be readily raised and lowered without moving the This crossf screen andthe shutters may be opened without swinglng the screen on its hinges, it

being necessary only to open the screen lid provided with upper and lower sashes and shutters, of shutter-operating devices connected with the shutters and with the sillof the window frame, a screen mounted outside the plane of the upper or outer sash, and a lid hinged to the lower end of the screen having an inner portion above the shutter operating device provided with a front arranged directly below the plane of the up! per sash close to the lower or inner sash and between said inner sashand the shutter operating devices.

2. The combination with a window frame, provided with upper and lower sashes and shutters, of shutter-operating devices connected with the shutters and with the sill of the window frame, a screen mounted outside the plane of the upper or outer sash, and a box-like lid above the shutter operating devices hinged to the screen and having a front portion disposed directly below the upper sash and close to the lower or inner sash and between said inner sash and the shutter operating devices.

3. The combination with the window frame, provided with upper and lower sashes and shutters, of shutter-operating with wire netting, and a box-like lid arranged over the connection of the shutteroperating devices with the sill, hinged to the lower end of the screen frame and having an inner front portion arranged directly below the upper sash and close to the lower or inner sash.

4. The combinationwith a window frame,

provided with upper and lower sashes and shutters, of a screen located outside the sashes and inside the shutters and having a recessed cross-piece, a lid hinged to the 1nside of the lower end of the screen frame and having a front portion located in a plane directly below theupper sashI and Slat-operating devicesd extending through the recessed cross-piece and having handles projecting into the lid portion of the screen.

5. The combination with a Window frame, provided with upper and lower sashes and shutters, of a screen 'located outside the' sashes and inside the shutters hinged to the window frame to swing about `a vertical axis, and a box-like lid hinged to the screen and having a front portion disposed directly below the upper sash and close to the lower or inner sash, said lid having one of its ends inclined to provide clearance when th screen is swung on its hinges.

6. The combination with a window frame, of. a frame hinged to the window frame to swing about a vertical axis, an awning attached to the frame sothat it may swing with said frame, and an awning-operating cord attached to the awning and extending through openings in the upper and lower cross-pieces of the frame; r

7. The combination with a window frame, of a screen hinged to the window frame to swing about a vertical axis and provided Lacasse BENJAMN F. LAUDENSCHLAGER JOHN S. FREDERGK Witnesses:
